BS or Master's degree?

I’m majoring in Art and wanted to know if I should get a BS or a Master’s degree?

I was thinking that getting a Master’s in Art would be ideal due to the economy and overall competitiveness for jobs in the art world. However, how much of a difference would getting a Master’s make, compared to just a BS?

I was also thinking that it might be wise to get a BA and major in something else, as well? It’s a lot of work, but I just really want to make sure I can get jobs once I’m done with school.

So: BS or Master’s? OR BS and BA? OR Master’s and BA? Help? Anyone?
